Released in the UK this June, Elvis & Nixon tells the strange-but-true story of the December 1970 meeting between US President Richard Nixon and singer Elvis Presley. The latest trailer for the riotous comedy, launching on the Telegraph, is shown below.

Michael Shannon and Kevin Spacey in Elvis & Nixon

During the famous encounter, which took place at the White House, the King of Rock ‘n’ Roll asked the US head of state if he could have a badge from the federal Bureau of Narcotics and Dangerous Drugs, and if he could become an undercover agent for the Bureau.

"The narc badge represented some kind of ultimate power to him," his wife Priscilla Presley later recalled in her memoir Elvis and Me (via Smithsonian Magazine).

"With the federal narcotics badge, he [believed he] could legally enter any country both wearing guns and carrying any drugs he wished."

In the film, directed by Liza Johnson, Kevin Spacey (no stranger to presidential impressions thanks to his role as scheming Frank Underwood in television series House of Cards) stars as Nixon, while Michael Shannon plays Presley.

Alex Pettyfer stars as music manager Jerry Schilling, while Colin Hanks (son of Tom) stars as Egil Krogh, a lawyer who later became implicated in the Watergate scandal.

A Seventies-style poster for the film, shown below, was released last month.

The photograph of the real-life Nixon shaking Presley's hand is the most-requested image from the US National Archives.
